ROCHESTER — Friday evening officials responded to reports of a structure fire in the downtown area after a fourth-floor bedroom reportedly caught fire on North Main Street.

The apartment building at 6 No. Main St., with tattoo shop "Body Creations" on the first floor, was evacuated at about 4:15 p.m.

Rochester Fire Marshal Dominick Bellio said there were no injuries at the scene, though paramedics from Frisbie Memorial Hospital continued to check and examine residents who were inside their apartments at the time of the incident.

Bellio reported the one-alarm fire was contained to the bedroom of its origin, though extensive smoke damage spread throughout the rest of the floor.

"A big building like this, it could have been really bad," he said.

The cause of the fire remains under investigation at this time.

Dozens of people stood behind the building, awaiting more information. Bellio added people inside the adjacent building, housing Kelly Gymnastics on the first floor, were also evacuated, though officials report the fire did not spread to that structure.

North Main Street was blocked off for short a period of time with Rochester police redirecting traffic around the center of the city. Fire trucks crowded the streets and local shop and restaurant workers took to the sidewalks to look on as a fire truck's ladder extended to the top of the affected building.

The Rochester Fire Department was assisted by the Frisbie Memorial Hospital EMS team, Rochester police and the Somersworth Fire Department.
